It is a common view, shared by Emergency Department staff and ambulance crews, that a large number of patients unnecessarily use Emergency Service ambulances instead of transporting themselves to the hospital by other, more appropriate means. In this retrospective study, 528 consecutive Emergency Service calls to the Herlev Hospital Casualty/Emergency Department during a six week period were reviewed for relevance. Attention was solely aimed at the relevance of the use of Emergency Service ambulances in each case, but not on patient or health care providers' perception of urgency. All calls resulting in admission to hospital were pre-defined as being relevant. Seventeen point six percent of all calls were deemed irrelevant. Thirty-three percent of all calls not resulting in admission were deemed irrelevant. The results confirm Emergency Department health care providers' and ambulance crews' view that Emergency Service ambulances are used inappropriately by the public.
Croup is a common pediatric respiratory illness presenting to the emergency department (ED) in the fall and winter months. Most cases are caused by parainfluenza viruses. We examine the monthly patterns of young children who made croup-related visits to EDs in Alberta, Canada.
Emergency department visits were identified in provincial administrative databases to obtain all ED encounters for croup made by young children (aged =2 years) during 6 years (April 1, 1999, to March 30, 2005). Time series models (seasonal autoregressive integrated moving average) were developed to capture temporal and seasonal trends and predict future presentations.
Overall, 27,355 croup-related ED visits were made during the study period. More males (62%) than females presented, and most (43%) were younger than 1 year. Differences were observed in the number of visits made in odd and even years. Peak visits occurred in November for odd years and in February for other years. Strong seasonal patterns at 12 months were detected and included in the modeling.
We observed the presence of a clear biennial pattern of croup ED visits. The seasonal autoregressive moving average models and predictions offer insights into the epidemiology of croup-related visits to EDs and may be helpful in planning both research and resource needs.
The composition of the causative agents of suppurations, isolated from suppurating wounds of patients hospitalized at different departments of the Sklifosovskii Emergency Aid Institute was studied. The proportion of representatives of different microbial families among more than 18,000 strains of the causative agents of wound infection was estimated. Fluctuations in the amount and structure of the agents were analyzed in different clinics over the period of 1967-1987. Under the conditions of emergency aid hospital Staphylococcus aureus proved to be the most frequent causative agent of suppurative inflammatory processes at different departments. At the same time no tendency towards an increase of the etiological role of any microbial family in the development of wound infections was noted. The incidence of different causative agents of suppurations was found to vary at different departments, depending on their specialization and season. The results of observations on the composition of the causative agents of wound infection may be used for the planning and evaluation of antiepidemic measures.
In Denmark political decisions to reduce traffic morbidity are often based on data collected from the police. It is often claimed that hospital-based traffic accident registration cannot provide detailed information regarding the exact localization of the accident. On the other hand, several investigations have shown a coverage of bicyclist accidents of only 8-19% in police records when comparing with hospital-based records. In the period from 1st of February 1995 until 31st of January 1997 all 971 patients injured in bicycle accidents and treated at the Emergency Department at Viborg Hospital were given a questionnaire regarding details about the accident and the exact localization of the accident. Eighty-five percent answered the questionnaire. Eight percent of the accidents were also found in the police register. From the material it could be concluded that six roads in the Municipality of Viborg were the scene of the accident in more than 10 cases each. A further analysis of these accidents pointed out two exact localizations on one single road as especially hazardous for bicyclists. It is concluded, that police-based registration of bicycle accidents are insufficient and more resources should be used on hospital-based accident registration, since detailed information about the site of the accidents also can be provided there.
